这是我根据百度云PCS的API写的一个基于bash的命令行工具,
使用了curl, awk, sed, xxd, bash,没有使用任何其他的语言解释器做辅助
目前,上传下载,文件列表,文件信息,创建文件夹,删除文件都没问题
复制和移动总是返回参数错误,实在找不出来哪里跟API不一致了,暂时放弃。
另外离线下载相关的API也都添加了,但是因为现在百度云不能申请,我是用的是bypy的client_id,
不知道它的离线下载相关权限没有抑或其他问题,添加任务返回500。
不过总的来说基本上对于一般使用百毒云是够用了

使用,假设保存成文件名bdcurl的执行文件:
如果想不用浏览器,而是直接在命令行授权给bypy来使用的话,需要在浏览器里登录 过百毒云,然后在cookie里找到BDUSS(可以用firebug,或者使用sqlite打开浏览器的数据库也能找到),把内容复制到脚本开头的 BDUSS变量里(这个有效期比较长,所以基本只复制一次就可以了,以后token过期后重新认证时可以省略这步),
bdcurl auth
等一小会就会输出token id,把这个段字符串复制到脚本开头的TOKEN变量里,然后就可以使用了。
如果不方便获取BDUSS,就需要把终端输出的网址粘贴到浏览器里获取一个code,然后把code替换
https://bypy-tianze.rhcloud.com/auth?code=$code&redirect_uri=oob&
里面$code的部分,获得最后的access_token放到脚本开始的TOKEN变量里。
然后命令行运行:
bdcurl h 看帮助
bdcurl u file1 down #上传文件到down文件夹
bdcurl f file1 down #快速上传文件(只向服务器查询校验信息,如果百度云上有相同的文件,则直接在建立该文件,不需上传,如果返回error_code,则百毒云上没有相同文件,需要使用bdcurl u上传文件)
bdcurl d down/file1 # 下载指定路径的文件
bdcurl del down/file1 # 删除指定路径的文件
bdcurl l down # 列出 down目录下的所有文件
暂时不支持批量上传下载,毕竟百毒本身没有这样的API,所谓批量得在客户端实现,但是bash来实现相对会麻烦很多,因为没有很好的解析json的方法,如果使用python,perl之类的辅助解析,那就不如干脆直接用python或perl写了。
另外输出结果使用一个compact函数对其做一定程度的简化,其简化程度可通过参数指定,脚本里默认(compact -ftbm, 倒数第四行)使用最大程度简化(如,去除花括号和方括号,去除fs_id,md5校验码,size文件大小,mtime和ctime创建/修改时间 等项目,如果传递参数里去掉-s则会保留size项),可以自行参看脚本里定义compact函数接收参数的说明,选择你合适的输出简化程度
